RAIL-JOINT.

T 0 all whom it may concern:

Be it known that I, POWELL ORGAIN ADAMS, a citizen of the United States,residing at Cameron, in the county of Milam and State of Texas, haveinvented certain new and useful Improvements in Rail-Joints, of whichthe following is a specification.

This invention relates to rail joints, and the object is to constructjoints for railway rails which will provide a smooth tread for thewheels of a locomotive or a train of cars and which will make the ointsas firm and rigid as any other parts of the rails and to provide lockingdevices to prevent displacement of the joints and to provide forexpansion of the rails without weakening the rails and joint by boltholes.

Another object is to construct such strong and durable joints that thecost of maintenance of the railway tracks will be much reduced, thenecessity of repairs being much reduced.

Other objects and advantages will be fully explained in the followingdescription and the invention will be more particularly pointed out inthe claims.

Reference is had to the accompanylng drawings which form a part of thisappl1 cation.

Figure 1 is a perspective View of a rail joint complete, constructed inaccordance with my invention. Fig. 2 is a perspective view of the jointblock. Fig. 3 is a side elevation of the joint block and the ends of twoabutting rails. Fig. 4 is a perspective View of the ends of two abuttingrails. Fig. 5 is a vertical section of a complete joint, the section ofthe joint block and one rail being taken along the line x-m of Fig. 3.Fig. 5 is a longitudinal section of the joint block. Fig. 6 is aperspective view of a complete oint, showing slight variation from thejoint shown in Fig. 1.

Similar characters of reference are used to indicate the same partsthroughout the several views.

Sections 1 and 2 of abutting rails are shown in the accompanyingdrawings. The contour of the ends of these rails is further shown inFig. 3, together with a side elevation of the joint block. The jointblock 3 forms a continuous tread between the ends of the abutting rails.The balls of the rails 1 and 2 terminate along the lines 4 and 5, 6 and7, and 8 and 9. The joint block 3 has a longitudinal groove in the underside Specification of Letters Patent.

thereof for receiving the web portions 10 of the abutting rails. Theball of the joint block 8 has an irregular contour to meet the irregularcontours of the balls of the abutting rails. The object of the irregularmeeting lines of the balls of the joint block and the abutting rails isto provide a continuous tread for the wheels. The wheel will be runningon the ball of the joint block before it leaves the ball of the railwhen approaching the joint and on leaving the joint the wheel will berunning on the ball of the rail before it leaves the ball of the jointblock. The joint block thus has portions of its ball lapping on portionsof the balls of the abutting rails.

The webs and the bases of the abutting rails are of the usualconstruction, coming in close proximity to each other. The webs 10 carrylocking lugs 11 on the upper sides at their ends and the joint block 3has a recess 12 in the under side thereof to receive the locking lugs.The locking lugs are not equal in extent as the recess 12, thusproviding for expansion and contraction of the rails. The lugs 11 andthe recess 12 provide a locking means to prevent displacement of therails. The lapped portions of the joint block on the balls of theabutting rails are of greater extent than expansion and contraction areestimated to be. The wings 13 and 14 of the joint block receive the websof the abutting rails and the flanges 15 rest on the flanges of therails. Bed plates 16 are provided for supporting the rail joint. The bedplate 16 extends longitudinally under the rails and rests on two crossties. The bed plate has a recess for receiving the bases of the railsand extend beyond the width of the rail bases and support the flanges 15of the joint block. The outer edges of the base plate have flan es 17projecting upwardly and downwardly. These flanges support the flanges 15and add strength to the base plate. The flanges 17 are cut away at thepoints where the bed plate crosses the ties.

This construction will prevent movement of the bed plate on the ties.Bolts 18 provided with nuts 19 and locks 20 for the bolts 19 bind thebed plate to the flanges 15 and thus clamp the ends of the rails.Ordinary spikes 21 bind the bed plate to the cross ties. Cleats 22 areplaced above the spikes 21 and secured to the bed plate flanges 16 bybolts 24 and suitable nuts. The cleats 22 thus serve to hold the jointblock in place and prevents the removal of the spikes from the track.

The joint block in combination with the base plate provides a jointWhich will be rigid and will prevent the vibration of the ends of theabutting rails.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is,

1. The combination of the abutting ends of railway rails, a joint block,and a bed plate, said joint block having a ball intercepting the ballsof said rails and having a longitudinal groove therein to receive thewebs of said rails and having a recess intermediate the ends of saidgroove and said webshaving lugs occupying said recess.

2. In a rail joint, the combination of the ends of abutting rails ajoint block having a longitudinal groove in the underside thereof, and abed plate secured to said joint block, said joint block having a ballinter: cepting the balls of the abutting rails along irregular lines andhaving a recess intermediate the ends of said groove and said railshaving webs extending in said groove and lugs carried by said webs lyingin said groove.

3. In a rail joint, the combination of the ends of abutting rails, ajoint block having a longitudinal groove in the underside thereof andhaving a ball intercepting the balls of said rails at diiferent verticalplanes, and a bed plate binding said joint block to said rails, saidabut-ting rails having webs occupying said groove and carrying lockinglugs on the upper sides of the ends of the webs and said joint blockhaving a recess to receive said lugs.

4. In a rail joint, the combination of the ends of abutting rails, ajoint block having a longitudinal groove in the underside thereof and arecess intermediate the ends of said groove and having a ballintercepting the balls of said abutting rails at different verticalplanes, a bed plate having a seat for the bases of said rails andvertical flanges on the edges thereof for bracing said joint block, saidrails having Webs 0ccupying said groove and said Webs carrying lockinglugs occupying said recess, bolts binding said block to said base plate,and cleats binding said rails to said base plate.

In testimony whereof, I set my hand in the presence of two witnesses,this th day of June, 1909.
